Software/Analysis

SHMS plastic scintillators

• Detector checks - stay tuned

• Calibrations

SHMS quartz plane

• Beam data analysis 1 - Analysis of March 2017 beam data

Detector updates/upgrades - SHMS quartz plane

Detector Modifications

• The XP2020Q and ET9814QB PMTs will be replaced by ET9814WB PMTs (going from quartz window to UV glass)

Detector Tests

• S. Malace is putting together a test setup in Hall C to test the quartz bars once they are fitted with new PMTs

• Low statistics cosmic run (8 bars) - Will update the plots as statistics accumulates
